    • A yarn winding mechanism includes a reference point through which the yarn always passes during yarn piecing-up and normal winding operations, a pair of yarn taking-out rollers disposed above the reference point, and a traversing device from which the yarn is wound onto a cone cheese. In order to cause the winding mechanism to soon begin and then continue the normal winding operation after completion of the yarn piecing-up, a device for compensating changes in yarn tension is disposed between the traversing device and the yarn taking-out rollers with a yarn guide surface extending generally parallel to the axis of the taking-out roller, and the upper taking-out roller is formed with a yarn catch in one end face edge thereof on the larger diameter side of the cone cheese, the yarn catch being arranged in an optimum position with respect to the parallelly extending surface of the tension compensating device and the reference point.

    • Disclosed is an open-end spinning machine which comprises a feed roller and a top roller for positively feeding a spun yarn from a spinning unit, a traverse guide for traversing the spun yarn in a direction perpendicular to the spun yarn feeding direction, a winding drum for frictionally rotating a conical surface bobbin for winding the traversed yarn to form a conical cheese, a guide or guides for absorbing yarn path length variations caused by the traverse motion of the spun yarn and by the conical angle of the conical cheese during the winding operation, a device for adjusting the guide in response to the conical angle of the conical cheese. By utilizing this machine, a good-shaped conical cheese of an open-end spun yarn having a uniform hardness along the axial direction of the cheese is obtained. Furthermore, this machine can be utilized for winding of various cheeses having various conical angles.

    • When an open end spinning machine is stopped, a fiber supply to a spinning rotor is first stopped and thereafter, substantially simultaneously with stoppage of both a yarn take-up roller and a yarn winding roller, a yarn end is held by a yarn holding device at a time when it still remains in a region which undergoes the suction effect of a subatmospheric pressure produced in the spinning rotor. The spinning rotor is subsequently stopped. On starting, the holding of the yarn end by the yarn holding device continues even after restarting of the spinning machine until the subatmospheric pressure produced in the spinning rotor reaches substantially the same value as that produced during a normal spinning operation. Therefore, there is prevented any snarling phenomenon, resulting in a greatly increased success rate in the operation of connecting yarn ends on re-starting of the spinning machine.
    • 当开放式纺纱机停止时,首先停止对纺丝转子的纤维供给,然后在纱线卷取辊和纱线卷绕辊停止的同时基本同时,纱线端部由纱线保持装置 此时它仍然保留在经受在纺丝转子中产生的低于大气压的吸力作用的区域中。 纺纱转子随后停止。 起动时,纱线保持装置的纱线端部的保持继续,即使在纺纱机重新起动之后,直到在纺丝转子中产生的低于大气压的压力达到与正常纺丝操作期间产生的大致相同的值。 因此,防止发生嘶嘶声现象,导致纺纱机再起动时连接纱线端部的操作成功率大大提高。

    • According to this invention, a spinning rotor is increased in speed until it reaches a predetermined higher speed beyond a lower speed region and then decreased in speed until it falls within the lower speed region, in which a yarn ending is effected. Thereafter, the speed of the spinning rotor is increased to a normal spinning speed beyond the predetermined higher speed. During rotation of the spinning rotor at the predetermined higher speed, sufficient subatmospheric pressure is produced in the spinning rotor to stretch out the yarn end thereby to prevent the yarn end from being snarled. Also, during this higher speed rotation of the spinning rotor, sufficient fibers in the spinning rotor can be collected in a maximum diameter portion in the spinning rotor to be connected with the snarl-free yarn end in a favorable condition. The period of time, during which the speed of the spinning rotor is decreased from the predetermined higher speed and falls within the lower speed region, is relatively short being in the order of a few or several seconds. Therefore, it will be understood that there is no fear that both the yarn end and the remaining fibers are restored to their initial state during that period of time.
    • 根据本发明,旋转转子的速度增加,直到其超过低速区域达到预定的较高速度,然后降低速度,直到其落入进行纱线结束的低速区域内。 此后,将纺丝转子的速度提高到超过预定的较高速度的正常纺丝速度。 在旋转转子以预定的较高速度旋转时,在纺丝转子中产生足够的低于大气压的伸出纱线端部,从而防止纱线端部嘶嘶响。 此外,在纺丝转子的这种较高速度的旋转中,纺丝转子中的足够的纤维可以收集在纺丝转子的最大直径部分中,以在有利的条件下与无卷曲纱线端部连接。 纺纱转子的速度从预定的较高速度降低并落在低速区域内的时间段相对较短,为几秒或数秒左右。 因此,应当理解,在该时间段内,纱线末端和剩余的纤维都不会恢复到初始状态。
